PRI-D 32 oz (2-Pack) Diesel and Kerosene Fuel Stabilizer

Professional-Grade Fuel Treatment for Long-Term Stability, Superior Lubrication & Engine Protection

PRI-D is a highly concentrated, complete diesel and kerosene fuel treatment, engineered to stabilize fuel, restore degraded fuel to usable condition, and protect modern engines, especially those running Ultra-Low Sulfur Diesel (ULSD). This 2-pack offers 64 oz total, thus treating over 1,000 gallons of fuel, making it ideal for long-term storage, generators, fleets, heavy equipment, or off-grid systems.

Whether you’re servicing farm machinery, getting ready for emergencies, or storing reserve fuel, PRI-D keeps your fuel fresh and helps safeguard your engine.

Why PRI-D?

🛢️ Stabilizes and Restores Fuel

• Prevents sludge, darkening, and breakdown in stored diesel or kerosene
• Revives degraded fuel to refinery-fresh quality—even after years in storage
• Proven in ASTM D2274 thermal stability testing

⚙️ Delivers Critical Lubrication for ULSD Systems

Modern ULSD fuel lacks the natural lubricating properties older diesel once had. This “dry” fuel increases wear on high-pressure pumps and injectors, leading to costly repairs.
PRI-D restores essential lubricity, reducing wear by up to 45% (confirmed by HFRR lubricity testing).

🔬 Improves Combustion & Efficiency

• Boosts power output and fuel economy
• Lowers emissions and carbon buildup
• Keeps injectors, fuel lines, and pumps clean

🧪 Safe, Proven Formula

• Contains no cetane boosters or harsh solvents
• Does not alter fuel specifications or void warranties
• Meets all major engine manufacturer requirements

Ideal Applications

• Emergency fuel storage (tanks, barrels, generators)
• Diesel trucks, RVs, boats, tractors, and industrial equipment
• Kerosene heaters and lamps
• Off-road diesel and biodiesel blends

Product Details

• Includes: 2 x 32 oz Bottles
• Treats: Up to 1,024 gallons (1 oz treats 16 gallons)
• Use: Shake well; add directly to fuel at each fill or before long-term storage
• Made in the USA

❓ Why Do Diesel Additives Matter?

Today’s ULSD fuel is required by law but lacks natural lubricity. This makes diesel components—like pumps and injectors—vulnerable to premature, even catastrophic failure. PRI-D replaces what refining has stripped away, offering both fuel preservation and system protection.

PRI-D 32 oz 2 Pack FAQ

Will PRI-D Provide Maximum Lubricity Protection?

Yes. PRI-D restores essential lubricity to ultra-low sulfur diesel (ULSD), helping reduce unnecessary wear on injectors and high-pressure fuel pumps.

Can PRI-D Improve Engine Performance?

Yes.  By maintaining fuel stability and supporting more efficient combustion, PRI-D enhances engine performance while helping to lower exhaust emissions.

Can PRI-D Help Reduce Maintenance Costs?

Yes. PRI-D helps prevent carbon buildup, sludge formation, and injector fouling, reducing maintenance and fuel system repair costs.

What Happens If You Over-Treat With PRI-D?

Over-treating generally does not cause harm. However, following the recommended treatment ratio ensures optimal performance and cost efficiency.
